dispensing particularly to apparatus Our invention relates in general to apparatus and more for dispensing fluids such as gasoline, although it may have more general application and one of the important objects of the invention is to provide means enabling the operator to control the entire apparatus at the dispensing nozzle.

More particularly we contemplate the provision, in a power-operated fluid dispensing apparatus, of means associated with a valved dispensing nozzle for controlling a remote power-operated fluid propelling device in connection with the control of the valved dispensing nozzle.

Another object is to provide an electrical control system for a power operated dispensing apparatus having means manually operable at the discharge nozzle of the apparatus for actuating the electrical system to start or stop the poweroperated apparatus.

Another object is to provide means for actuating the electrical control system at the discharge nozzle without interrupting an electrical current carrying circuit, thus to eliminate sparking and the resulting danger of explosions where inflammable fluids are dispensed.

Another object is to provide an electrically controlled power operated dispensing device for inflammable fluids with means for actuating the electrical control system from the dispensing nozzle without danger of exploding the inflammable fluid being dispensed.

Another object is to provide an automatic, electrically operated, locking device to prevent unauthorized operation of the dispensing device.

Another object is to control the dispensing deacteristics of an electric control circuit without interrupting the circuit and thus creating sparks.

Among the other objects and advantages is to provide a simple, inexpensive and safe electrical remote control for a fluid dispensing device; to provide a fluid pressure dispensing device having a valved nozzle with means adjustable to permit the nozzle valve and the fluid pressure control to be actuated in a desired sequence so that the control system maybe conditioned to 'open the valve before or after or at the same time the dispensing pressure is applied to the fluid to force it through the nozzle; to provide a fluid dispensing device, having a flexible discharge hose terminating in a valved nozzle and means to force the fluid under pressurethrough the hose with an electrical remote control system including electrical means operable from the nozzle to control the operation of the fluid forcing means without breaking the electrical circuit at the nozzle or in the immediate neighborhood of the hose; and in general to provide numerous other improvements and advantages which will become more clearly apparent from the following description, which, 5 taken with the accompanying drawings, discloses a preferred form of the invention.

I To illustrate our invention, we have shown on the drawings, a fluid dispensing device including a preferably flexible fluid dispensing conduit or hose II terminating in a nozzle I3 and means to force the fluid to be dispensed to the hose I under pressure. The fluid forcing means may comprise any suitable means but we prefer to employ a pump l5 which is driven by any suitable or convenient motive means I1, the operation of which may be quickly and easily controlled.

In the illustrated embodiment, the device I! comprises an electric motor and the intake of the pump I5 is connected by means of a suitable conduit IS with a storage tank 2| for the fluid to be dispensed. The outlet of the pump is connected by means of a conduit 23 to an air release and overflow device 25 and thence by the conduit 21 through suitable metering devices in the housing or standard 29 and through the sight glass 3| to the hose II. The air release device also may have a vent 33 and a return connection 35 to the reservoir 2|. g

It will be noted that the pump l5 and its driving motor III, i. e., the devices for forcing the fluid to the nozzle l3 under pressure are shown located in the house 31 at a point remote from the standard 29. The fluid forcing means can, of course, be located in the housing 29 if desired but in any event it is desirable to control the operation of the fluid forcing means from the nozzle so that the operator may start and stop the same while manipulating the nozzle in dispensing fluid. To this end the fluid forcing means is actuated from a suitable electrical power source 39 by means of conductors 4| which lead from the power source through suitable switching and protective devices 43 to the electric motor I1. The conductors 4| also are provided with a control switch 45 normally urged by the spring 41 toward open position but operable by means of the solenoid 49 to close against the influence of the spring 41. The solenoid 49 is included in an electrical circuit 5| including the power source 39, the switching and protective devices 53 and the control device 55. In addition, the circuit may, if desired, include a locking device 51, the operation and function of which will hereinafter be more fully explained. The conductors 4| may and the circuit 5| should, respectively contain switches 58 and 59 preferably mercury switches, which are preferably operatively connected to the tiltable hook 6| carried on the housing 29 and on which the nozzle I3 is adapted to be supported or hung when not in use. The hook is preferably normally moved toward a raised position on the housing 29 by means of the spring 63 and the switches 58 and 59 are arranged to close when the hook is raised by the spring, i. e., when the nozzle is off the hook and ready for action, and to open when the hook is depressed against the urge of the spring by the weight of the nozzle hanging inactively upon it. Alternately the hook 6| may be manually shifted to either raised or lowered position.

When the nozzle is hanging on the hook therefor, the switches 58 and 59 are open and the circuits 4| and 5| are inactive.- When the nozzle is removed from the hook, however, the switches 58 and 59 will close and the motor I1 would immediately be set in operation but for the fact that the switch 45, which is open, must be closed before the motor can be started. The motor, therefore, does not start when the switches 58 close as a result of the removal of the nozzle from the hook. When the switch 59 is closed, however, the circuit 5| will be closed and in operating condition. The nozzle I3 embodies a valve 65 which is normally urged by means of the spring 51 to close the nozzle against the discharge of fluid therethrough but has a stem 69 which may be moved to unseat the valve against the urge of its spring. The control mechanism 55 in the circuit 5| is for the purpose of controlling the amount of electrical current flowing in the circuit 5| and is arranged when in normal position, i. e., when the nozzle is closed by the valve 65, to prevent sufficient current from flowing in the circuit 5| to actuate the solenoid 49 to close the switch 45. The control 55, however, is arranged to increase the current in the circuit 5| sufficiently to close the switch 45 whenever the valve stem 69 is depressed to open the valve 65 so that when the nozzle is off the hook and the valve is opened, the motor I1 will be started in operation to force the fluid out through the nozzle; and the parts may be adjusted to cause the motor to start in operation just before or after or at the same time that the valve is opened. To this end the nozzle comprises a fitting having a channel 1| formed for connection at one end with the hose II, preferably though not essentially, through a fitting 13 containing a valve 15 opening outwardly into the channel 1|. The opposed end of the channel 1| is provided for the actual discharge of the fluid. The fitting also provides a valve seat 11 intermediate the ends of the channel 1| for the valve 65 and a packing gland or bushing 19 may be provided to permit the valve stem to extend out of the fitting in position to be manually depressed by the operator. The nozzle fitting also may be formed as shown in Fig. 3 to provide a mounting for the control 55 which, in the illustrated embodiment, comprises a coil 8| connected in the circuit 5| and wound preferably on the middle arm of an E-shaped core 83, which may be secured in any suitable manner in a casing 85. This casing provides room adjacent the core for a shiftable armature 81 carried on a shaft 89 which extends out of the cover 9| of the casing and terminates in a shackle 93. Within the casing a spring is provided to normally urge the armature 81 to engage and bridge the gap between the ends of the arms of the core. The armature, however, may be retracted against the urge of the spring to increase substantially the air gap in the core of the control device 55. By increasing the air gap the magnetic characteristics of the device are changed so that more current may flow through the coil in response to an electro-motive force of given voltage applied to the circuit 5|. In other words, by increasing the air gap in the core of the device 55, more current is permitted to flow in the circuit 5| and the parts are arranged so that when the armature is lifted from the core a predetermined distance, the current in the circuit 5| is increased to a point permitting the switch 45 to close against the spring 41. In order to operate the device 55 in conjunction with the valve 65, a handle 91 is pivoted on the nozzle fitting in position to extend across the protruding end of the valve stem 69 and is shaped to enable the operator to easily grasp it. The free end of the handle is formed as at 99 to co-operate with the cam slot |0| of a lever I03, which is pivoted in the nozzle fitting and which is attached to the shackle 93 of the device 55 by means of the loose pin I05. As the operator manipulates the handle 91 to depress the valve stem 69, the cam follower 99 traveling in the slot |0| will draw the armature 81 away from the core and start the fluid forcing means in operation. The support for the device 55 may be formed as a guard I01 for the handle 91 and the lever I03. The handle 91 also may carry an adjustable screw I09 opposite the end of the valve stem whereby to adjust the operation of the valve in any desired timed relation with respect to the device 55 and the guard I01 may be perforated as at III to accommodate the adjusting screw. Means is provided to lock the nozzle on the hook 6| when not in use. The housing 29 is provided with a receptacle I25 to receive the discharge end of the nozzle fitting and the hook has a pin 62 while the guard I01 is provided with a finger I08 adapted to rest on thepin 62. The guard also is provided with an open- 'ing I26 to receive a projection I21 on the hook,

which projection is formed to receive a locking device I29 to secure the nozzle on the hook and to hold the levers 91 and I03 in the inoperative position shown in Figs. 2 and 3.

The switch 45 is preferably of the toggle type, that is to say, one which makes or breaks contact rapidly so that the switch passes from open to closed position or vice versa practically instantaneously at the appointed instant of operation. The spring 41 also is preferably provided with a means 48 for adjusting the tension thereof in order that the instant of operation of the switch may be regulated to a certain extent by increasing or decreasing the spring tension which operates differentially with respect to the electro-magnetic tion so that the system may be conditioned to operate in a desired sequence. In certain in stances, it may be found desirable to provide the switch with means to delay both opening and closing movements.

By means'of the adjustment provided by the set screw tilt, the system may be conditioned so that the motor'starts after the valve is opened and stops before the valve closes or the adjustment may be arranged to cause the motor to start before the valve is open and to stop after the valve closes. It is not essential that the adjustment be provided between the handle til and the stem 69 of the valve but it may be applied between the handle 97 and the operating plunger of the electro-magnetic control device 55 in order to control the movement of said operating plunger in conjunction with the movement of the valve plunger t9.

By delaying the opening movement of the switch t5, the stoppage of the motor may be delayed to occur after the valve 55 closes even when the adjustment the is set to start the motor after the valve opens so that by means of the switchopening time-delay device, the motor may be made to start after the valve 65 opens and to stop after the valve t5 closes. By delaying the switchclosing movement, the starting of the motor may be delayed until after the valve is open even where the adjustment the has been set to accomplish the stoppage oi the motor before the valve closes in order that the system maybe conditioned so that the motor starts after the valve opens and stops before the valve is closed.

In other words, the system of our present invention is adjustable to open and close the valve and start and stop the motor in any desired sequence. The motor can be made to start before the valve is opened and to stop before the valve is closed; to start before the valve is opened and to stop after the valve closes; to start after the valve opens and to stop after the valve closes; and to start after the valve opens and to stop before the valve closes. This flexibility in operation has numerous advantages which will be appreciated by any one familiar with this type of apparatus.

As a safety measure and to prevent the device from operating at all unless all parts are functioning properly, we have provided an electrically operated automatic self-locking device 5i comprising a solenoid H3 which is connected in the circuit at and hence energized only when the circuit M is energized, that is to say, when the switch 59 is closed by removing the nozzle from the hook iii. The solenoid its is mounted in a fitting H5 threaded in an opening in line with the valve seat ii and formed to receive an extension ll of the valve stem 69. The extension has a groove lit to receive the looking tip of a member m which is carried in the fitting M5 andnormally urged toward locking position by the spring I23. The member Mi, however, also forms the armature of the solenoid H3 so that when energized, the solenoid will retract the armature and permit the valve -through a guide i159 be found desirable to provide switch means in the motor power circuit ll and to control the switch by means of an under voltage relay powered from the circuit 50 so that if, for any reason, the circuit 5i is not energized when the hook El is released, the under voltage switch means will open and prevent the motor from operating when the control circuit is inoperative.

The devices 55 and W are, of course, located on the nozzle but it will be noted that they simply comprise coils of wire and no electrical circuit is opened at the nozzle. The switches 59 and Eli are sealed mercury switches and are preferably located within housing ill and hence no sparking is permitted at any spot in the vicinity of the discharge of the'fluid. The conductors forming the part of the circuit ti leading to the coils of the'devices bband 5'?! are preferably thoroughly insulated and clad in a flexible metallic sheath iii which may parallel the hose ii and be secured thereto by suitable clips H33.

In Figs. 8, 9, and 10, we have shown other embodiments of our invention wherein the control of the power operated fluid forcing means 05 is accomplished by pulling the hose out of its normal free hanging position as when the operator pulls the hose into position to deliver gasoline to an automobile. In these arrangements the motor control, after the system has first been conditioned for operation by removing the nozzle from the, hook, is accomplished by a device W5 which, as shown in Figs. 8 and 9, has a func-.

tion similar to that of the device 55 previously mentioned, or if desired, may be a switch. The device W5 may be mounted on the casing dt, as shown in Fig. 8, or may be mounted on" the hose H, as shown in Figs. 9 and 10. If mounted on the casing, the shiftable element of the device may be connected, by a rigid or preferably by a flexible connector ib'l, to the hose M at a point spaced from its point of attachment on the housing 29'. The connector lfil also extends rigid with the housing 29 and located adjacent the hose ll, so that if the hose is pulled in any direction away from the rigid guide, as it must be to assume any position other than a free hanging position, the connector will be pulled out through the guide and will actuate the device M5 to control the fluid forcing means. The hose may be pulled by the operator in manipulating the nozzle which may, in this instance, be similar to the nozzles shown in Fig. 3, the parts 5t, 51, and W3 and functionally associated parts being eliminated.

Where the control device W5 is mounted on the hose as in Fig. 9, it is simply necessary to connect the shiftable element of the device to the closest point on the casing 29 by means of a rigid or flexible connector, so that when the hose is shifted from its freehanging position in any direction other than toward the housing itself, the operative parts of the device will be relatively shifted and the desired control effected.

In the embodiment of our invention shown in llll Fig. 1Q, the upper part of the flexible hose may and I8! corresponding to the parts BI and 81 of Fig. 5 and arranged form, the part l8! being mounted stationarily on the upper portion of the sylphon and the lower or relatively movable portion of the sylphon carrying the shiftable core I81 like 81 of Fig. 5 mounted concentrically thereon and flexibly shiftable toward and away from the parts l8l, so that when the hose is pulled the sylphon will be stretched and the core part 181 will be shifted with respect to the stationary coil parts I81 whereby to alter or change the flow of current through the circuit 5| as heretofore described in connection with the device of Fig. 4. Such a form of device will be operable on pulling the hose in any direction. The natural tendency of the flexible or resilient sylphon to return to normal position would restore the control device in like manner to the action of the spring of Fig. 5. In place of a sylphon, any approved type of resilient coupling having relatively shiftabie parts may be used, it being understood that when the hose is pulled, one part of the coupling will be moved relatively to the other, and these parts would be provided with the electrical control device of Fig. 5.

In accordance with another embodiment of our invention, we propose as shown in Figurev 11 to provide the housing 29 with an upper overhanging portion lfll enclosing a rotatably mounted drum I43, adapted normally to be rotated in one direction by suitable spring means. This drum is provided with an axially located conduit or pipe I45 which may be connected to the discharge of a sight glass, orto the discharge of the meter through which gasoline is forced from the pump. This axial pipe terminates in a flex-' ible hose H which normally coils on the drum. The end of the flexible hose is provided with a valve controlled nozzle l3, and the nozzle is adapted to project through an opening M1 in the housing, the arrangement being that when desiring to dispense gasoline, the operator grasps the projecting nozzle and pulls so as to rotate the drum and draw out the hose to desired length. The drum is provided with a lug I49 adapted to move a control lever I5l when the drum is rotated to shift suitable control means, such as a mercury switch I53, to start the pump motor. Suitable adjustments are provided for regulating the time at which the pump motor starts when the drum is rotated. On return movement, the operator lets the spring rotate the drum to coil the hose' upon the drum within the'housing. Preferably a hand controlled leveris proyided for pre-setting the motor starting mechanism which thereafter becomes automatically operable on rotating, the drum by a pull on the hose. This is necessary in order to comply with fire 'under-. writers demands. In this rotating drum type of device, the housing is provided with a shutter or closure which locks the nozzle in the housing except for only a portion of the discharge end.

The main portion of the nozzle is wholly enclosed, and hence the valve lever or control cannot be operated inadvertently. The shiftable shutter on the housing may be padlocked in closed position. Thus, in this device, rotation of the drum in one direction through a desired angular degree, automatically starts the pump, and after the finish of the dispensing operation, the rotation of the drum by the spring, automatically actuates the mechanism to stop the pump. The lug for shifting the pump motor starting lever may be angularly adjustable on the drum to conin collar or sleeve-like trol the time of starting and stopping the motor of the pump. Suitable means is provided for controlling the tension of the spring urging the drum to rotate so as to control the speed of the winding and unwinding of the hose. By having the drum elevated so that the nozzle depends at a suflicient elevation, better access is had to the hose and more facility in the unwinding, and particularly the winding operation is provided, and no particular support need be provided for the depending hose. vThe starting and stopping of the pump motor is controlled by pulling out the hose, this causing rotation of the drum, and the automatic operation of the pump motor.

, The constructions shown in Figs. 8, 9, and 10 are simple and inexpensive and have the advantage that the control device is removed from theimmediate neighborhood of the nozzle. If desired, the automatic locking device may be incorporated in the embodiments shown in Figs. 8, 9, and 10 and also may be omitted in the embodiment first described herein, since the same, while a useful improvement, is by no means an essential feature.

It is thought that the invention, and its numerous attendant advantages, will be fully understood from the foregoing description and it is obvious that numerous changes may be made in the form, construction and arrangement of the several parts without departing from the spirit or scope of the invention or sacrificing any of its advantages.
